Freya exhibits striking silver hair and eyes paired with fair skin and a figure embodying the golden ratio. Her typical attire features revealing black and red garments adorned with floral hair ornaments, accentuating divine beauty. A magical arrangement allows her appearance to alternate with Syr Flova, a waitress identity characterized by tied-back hair and a standard uniform at the Hostess of Fertility tavern.

Her personality blends charm, impatience, and profound obsession. She displays a flirtatious, teasing demeanor while harboring intense fixation on acquiring talented individuals—particularly Bell Cranel. This drives her to manipulate events, accelerating Bell's growth even through endangerment, and eliminating rivals like Ishtar. Freya feels jealousy toward Bell's interactions with Ais Wallenstein but refrains from harming Ais directly. Though free-spirited, she tolerates her familia's stifling protectiveness. Her actions escalate to extremes, including brainwashing Orario's populace to claim Bell, demonstrating willingness to inflict widespread suffering for her goals.

Centuries before current events, Freya lost a challenge to Hera and Zeus, binding her to Orario and costing several familia members. Later, she rescued a girl named Syr, forging a pact: Freya gained Syr's appearance and name, while the girl became "Horn" and could transform into Freya. This enabled Freya to operate incognito as Syr, working at the Hostess of Fertility and befriending staff like Ryuu Lion. As Syr, she initially provided Bell meals and support, gradually developing genuine affection alongside her divine obsession.

Freya wields innate powers:
- **Discerning Eye**: Perceives soul colors and brilliance, revealing emotions and mental states. Bell's transparent soul fascinates her; Ais's appears gold. This aids in estimating adventurers' capabilities and manipulating others through psychological insight.
- **Charm**: Her divine beauty enthralls gods, mortals, and monsters, causing effects from absolute obedience to sensory overload, memory alteration, or erasure. Only Bell (via Liaris Freese) and Hestia (as a Virgin Goddess) resist. She once charmed all Orario to isolate Bell.
- **Arcanum**: Includes creating Divine Mirrors for remote observation and, via her pact with Horn, maintaining her Syr disguise despite divine restrictions.

She leads Orario's most powerful familia, based in Folkvangr mansion. Members include Ottar (the city's sole Level 7 adventurer), Allen Fromel, Hogni Ragnar, Hedin Selland (Level 6), and four Level 5 adventurers. The familia enforces her will, such as destroying the Ishtar Familia. Freya values their loyalty but finds their protectiveness stifling.

Key relationships define her:
- **Bell Cranel**: His transparent soul captivates her as Odr's potential reincarnation. She alternates nurturing him as Syr with orchestrating trials to hasten his growth. After Bell rejects her confession, she brainwashes Orario in a failed claim attempt. Post-Great Faction War, she acknowledges his rejection but vows eternal pursuit across lifetimes.
- **Ottar**: Rescued by Freya as a child, he is her most trusted warrior. She values his perspective on her "equal love" for followers, deepening her affection.
- **Mia Grand**: The dwarf resisted Freya's charm, earning Freya's admiration and funding for her hometown. Mia treats Freya normally, becoming a maternal figure to the Syr persona.
- **Ryuu Lion**: As Syr, Freya rescued and employed Ryuu at the tavern. Despite friendship, Freya charmed Ryuu during the Orario incident but later released her, offering to "share" Bell.
- **Hestia**: Freya respects her as the Sacred Flame Goddess but retaliates when mocked over Bell's rejection.
